Definitions
- the invention concerns a mechanical system, forming a cam follower or a rocker arm, and comprising a pin or a roller.
- the invention also concerns an injection pump or a valve actuator comprising such a mechanical system.
- the invention also concerns a method for manufacturing such a mechanical system.
- a cam follower comprises at least a tappet, a pin and a roller.
- the tappet extends along a longitudinal axis, while the pin and the roller are centered on a transversal axis.
- the tappet is formed with two lateral flanges, delimiting an intermediate gap between them and each comprising a cylindrical bore.
- the roller is positioned in the intermediate gap, between both flanges and bores.
- the pin is fitted in the two bores, such that the roller is movable in rotation relative to the pin around its axis.
- the pin may be caulked, in other words plastically deformed, on both opposite ends to create a mechanical connection by press-fit in the tappet bores.
- the roller collaborates with a cam synchronized with the internal combustion engine camshaft.
- the rotation of the camshaft leads to a periodic displacement of a piston of the pump that rests against the tappet, to allow fuel to be delivered.
- the tappet is movable back and forth along the longitudinal axis in a bore belonging to the injection pump, with the cylindrical outer surface of the tappet sliding in this bore.
- the roller is movable in rotation around its central axis.
- the body of the tappet is in one piece, made by forging.
- the tappet As shown by example in EP-A-2 607 636 , it is known to provide the tappet with a single piece body equipped with two flanges having holes for supporting the ends of the pin on which the roller is mounted.
- the holes in the flanges each have a radial recess adapted to receive a plastically deformed radial portion of the caulked end of the pin.
- the roller is mounted between the flanges of the tappet. Then, the pin is inserted in the roller, through the holes of the flanges, the ends of the pin being supported by the flanges. Then, the ends of the pin are caulked.
- the assembly of the tappet is time consuming. Besides, the body of the tappet has to be machined, which is long and expensive.
- the aim of the invention is to provide an improved mechanical system easy to assemble and having a reduced cost.
- the invention concerns a mechanical system forming a cam follower or a rocker arm, the mechanical system comprising a support element, a pin extending between two opposite ends along a first axis and supported by the support element, and a roller mounted on the pin, movable in rotation relative to the pin around the first axis and adapted to roll on a cam.
- the mechanical system further includes an insert made from separate parts and including holding members supporting the pin ends.
- the insert allows to easily mount the pin.
- the mechanical member is cheaper to produce.

- Another aspect of the invention concerns an injection pump for a motor vehicle, comprising a mechanical system according to the invention.
- Another aspect of the invention concerns a valve actuator for a motor vehicle, comprising a mechanical system according to the invention.
- Another aspect of the invention concerns a method for manufacturing a mechanical system according to the invention, wherein:
- the insert, the pin and the roller are inserted inside the support element until the insert comes into abutment with first abutment means.
- the method may further include a subsequent step wherein second abutment means are made by stamping a cylindrical wall of support element, for blocking the translation of insert in a direction parallel to the longitudinal axis.
- the mechanical system 1 represented on figures 1 and 2 is of the cam follower type, adapted to equip an injection pump for a motor vehicle, not shown.
- Mechanical system 1 comprises a support element or tappet 10, an insert 20, a pin 30 and a roller 40, together forming a plain bearing.

- Axes X1 and Y1 are perpendicular and they have a point of intersection P1.
- Roller 40 is adapted to roll on a cam 2, partly shown on figure 1 only, in centerline. More precisely, an external surface 41 of roller 40 can roll on the outer surface of cam 2. When cam 2 and roller 40 are cooperating, a force F is applied on surface 41 along longitudinal axis Y1.
- a cavity C is delimited inside tappet 10. This cavity C is adapted to receive a shaft or plunger, not shown, for moving tappet 10 along axis Y1. Tappet 10 is movable back and forth along axis Y1, in a non-represented bore belonging to the injection pump.
- Tappet 10 has a cylindrical wall or skirt 11 centered along longitudinal axis Y1, with a first end or lower end 10.1, on the side of plunger, and a second end or upper end 10.2 on the side of pin 30 and roller 40.
- An internal surface S11 of cylindrical wall 11 delimits cavity C.
- Insert 20 is made of three separate pieces and includes a first holding portion 20A and a second holding portion 20B generally parallel with longitudinal axis Y1, and a connecting portion 20C perpendicular to holding portions 20A and 20B.
- Each holding portion 20A and 20B is provided with a blind circular recess 21 for receiving one end 35 or 36 of pin 30.
- Recesses 21 are centered on transversal axis X1 and have a diameter slightly higher than to the diameter of pin ends 35 and 36.
- Holding portions 20A and 20B have a convex external surface S20 curved like a portion of cylinder having a diameter roughly equal to the diameter of an internal surface S11 of tappet 10.
- Pin ends 35, 36 extend on one side and another of a first part 39 of pin 30, this part having a diameter higher than the diameter of pin ends 35 and 36.
- a shoulder 37 perpendicular to transversal axis X1 is located between first part 39 and each pin end 35 and 36.
- first axial clearance K1 between each pin end 35 and 36 and the bottom of the corresponding recess 21.
- second axial clearance K2 between each shoulder 37 and an internal surface S21 of the corresponding holding member 20A or 20B, into which recesses 21 are excavated.
- Axial clearances K1 and K2 are parallel to transversal axis X1.
- Connecting portion 20C is a flat disc perpendicular to longitudinal axis Y1, having a diameter roughly equal to the diameter of internal surface S11 of tappet 10.
- Each holding portion 20A and 20B includes several legs 22 protruding towards lower end 10.1 of tappet 10, for example two legs. Each leg 22 if fitted into a corresponding notch 23 of connecting portion 20C.
- Connecting portion 20C is made from a metallic sheet, or by metal sintering. It transmits the load F to the plunger.
